I thought these blueprints might be useful for NFA personell as well as reference material for legal semi-auto builds. Know the the Federal as well as your local area laws before even attempting any such endeavor. Do yourself a huge favor and keep it legal. I shouldn't have to remind anyone of that on this sight.
